.' Registers, of which the followin is a full,

clear, and exact description, re erence being had to the accompanying drawings,

part of this specificatmn. 1 Our invention relates to electrically operated autographic registers, wherein an elec- I tric motor is provided which feeds the paper llif perfect almement' to a point for tearing o There has not been, to our knowledge, a successful motor operated autographic register in the past because the control of the feed has presented a difficult problem. It isnecessary for the operator to touch a button to start the motor, and it should be provided that the device will come to a stop at the end of one complete feed of a section of the paper strips, whether the operator carelessly leaves his finger on the starting button or not. Then again,-except in the type of feed of paper known as the Standard register or pin wheel feed as first developed in the patent to Schirmer, No. 940,481, it would be difiicult to provide for proper feed'by sections of the paper in a purely automatic manner with positive stops as arenecessary between operations.

Thus it is our object to provide an electric motor feed for autographic registers which is fool-proof and eflicient and which may be readilyattached to any Standard register or other type of machine wherein the feed of strips is accurately gaged by the operating dBVlCBS;

These objects are accomplished by that certain construction and arrangement of.

parts to be hereinafter more. specifically pointed out and claimed.

In the drawings,

naled at the outer end in a small journal 6 on the plate and is equipped at the end with .a worm 7 Keyed over the feed shaft 8 of the register, which draws the slips of paper over the writing table portion of the register is the controlling cam 9,-on the outer face of which is frictionally secured'by means of facial contact therewith, the small toothed pinion or worm wheel 10. It can be seen that when the motor operates the worm will drive the operating shaft and continue to do so as long as the current is on and the cam is free to move. f r

It is our urpose to provide a simple device for lociiing and unlocking the controlling cam, which device will stop the cam at sin le revolution, thereby preventing the slig test overthrow and providing a per-' fectly evenfeed of the paper in the desired sections. To this end there is rovided the latch arms 11 and 12, with the atch arm 12 slidably mounted on the arm 11 by means of screws 13 sliding in slots 14 in the arm 12. The arm 12 operates the switch and ispulled downwardly at the outer end by the spring 15 which pulls downwardly the arm 11. The arm 12 is moved rearwardly by the spring 16 which is secured at its otherend to the upper arm 11.

When in normal locked position, the arm 12 engages over the shoulder 16 of the controlling cam, by means of its hooked nose 17 The arm 11 has alSO a nose 18 which when the device is in normal position abuts the nose 17 on the outer edge thereof.

Mounted on the plate 1 behind the motor is a bracket 19, in which slides a reciprocatspring-pressed pawl 22 which stands normally on a line with the plunger. This pawl lies when in normal position with its end pressing down on the cut-away end portion 23 of the under arm 12. Upon depression of the plunger the end 23 of the arm 12 will be depressed. This arm is mounted, as stated, on the arm 11, and the arm 11 is pivoted at 24 in a small frame 25 on the plate 1. Thus the downward movement caused by the pawl will cause the two noses to be lifted off the shoulder on the cam and will leave it free to revolve.

The small pawl will be thrown out of the vertical by the nose 26 back of the cut-away end of the arm 12, as it moves rearwardly under spring tension, and as long as the plunger is kept in depressed position the pawl will remain tipped as it is thrown off center and will slide along the said cutaway end of the arm. The arm can rise up again at the inner end, due to its outer end falling over the nose of the cam, as will be described without affecting the plunger or the pawl, except to swing the pawl farther out of the vertical, and until the plunger is released it will be impossible to again depress the arm 12 at the inner end.

Leaving the switch for the present out of consideration, so as to describe the operation of the latch arms first, the controlling cam 9 being keyed to the feed shaft 8 of the register is operated counterclockwise as indicated' by the arrows on Figs. 1 and 2, and during this rotation after the noses or hooks 17, 18, are raised by the depression of the plunger 20, they will be held by the spring 15 in contact with the periphery of the cam, and ride around this periphery in position to come in contact with the shoulder 16 on the cam at the end of the revolution.

As illustrated in Fig. 1, the two latch arms 11 and 12 will be separated when the machine is at rest with the two hooks 17 18,

.on the latches brought together. As soon as the latches are raised by the depression of the plunger 20, the spring 16 will 'bring the curved surfaces of the latch arms together and separate the hooks 17 and 18 as shown in Fig. 2.

It was stated that the arm 12 operates the switch. This member comprises a spring bar 27 which is fastened to one of the com tacts at 28 and when released will moveby its inherent springiness into contact with the other contact 29. Pivoted at 30 to the plate 1 adjacent the frame which pivots the latch arms, is a bar 30 which is curved and has at its lower end a fiber or insulated pin 31 which swings the spring bar of the switch out of contact when the upper end of the said bar 30 is moved toward the controlling cam end of the device. The bar 30 is slotted at 32, and a pin 33 on the under arm; 12 rides in the slot,

When the end 17 of the under arm is raised by the pawl as described, spring 16 will move it to the right or rearwardly and therebymove the pin in the slot 32 so as to release the bar 30 and permit the spring bar of the switch to move to closing position.

As the switch is then closed the motor will operate, and as the cam is released or unlocked the motor will revolve the cam and cause the register to feed.

The feed will continue until the shoulder 16 on the cam comes in contact with the hook 17 and by this contact the latch arm 12 will be shifted to bring the hook 17 in contact with the hook 18 of the other latch arm 11. At the same time themovement of the latch arm 12 will through the pin 33 swing the bar 30 so as to open the switch 27. This will'cut off the power of the motor before the two hooks 17 and 18 are brought together and the cam brought toa. fixed stop. The motor, therefore, is not brought to a fixed stop at the same time that the current is cut off and in addition to this, inasmuch as the worm wheel 10 is loosely mounted on the feed shaft 8 and drives the shaft through the cam; disk 9 with which it has frictional engagement as heretofore de scribed, there is no danger of burning out the motor, although the feed shaft itself for the paper strips is brought to. a full definite stop when the controlling cam has shifted the under latch arm into the position shown in Fig. 1 to bring the two hooks 17 and 18 together.

It is'believed that the above description sufiiciently describes the operation of the machine without further detailed description. It should be noted that various equivalent devices could readily be devised for accomplishing the purposes of the above structure, and that the failure to mention those during the description of the device was not intended to effect a limitation of the claims that follow.

The .various objects primarily stated are accomplished. The operating device is positively stopped at the end of each operation, and the continued depression of the tripping pawl will not result in the motor continuing to operate or the switch remaining closed, and a convenient and practical device is provided which gives motor operation to an autographic register.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is v 1. In a motor feed device for intermit tent feeding devices, in combination with electric motor means for operating the feeding device a switch therefor, and a controlling device comprising a rotary notched element, ,a pivoted arm havin a nose to ride on said rotary element, an to latch into said. notch, and. a pawl to rock said arm,
